A long line of Saharan dust swept across Mali, Mauritania, and Western Sahara and out over the Canary Islands on March 3, 2004. The dust appears to have originated in Algeria. Winter and spring dust storms are common in Western Africa when the sirocco winds — hot, dry, dust-laden winds — blow north and northwest out of the Sahara Desert. Later on the same day, the Aqua satellite recorded a similar scene. As the day progressed, the dust grew thicker and the storm extended farther west. This image was taken by the Terra MODIS instrument.

I love these Modis topics. They have a lot of interesting information in them.
